We've been trying to get fibre connected for months and have had a number of Chorus visits, but still no success.

We have buried copper phone cables and we see where they enter the basement. However, where they enter the house they are in flexi-conduit, which Chorus say is not suitable for fibre. Somewhere near the house, the flexi-conduit must become rigid conduit, which will them go to the pole near our property. This would be suitable for fibre, but up till now we haven't been able to find the rigid conduit.

However we had a dig in a random spot and found a wide black conduit (say 50mm) and next to it a smaller (say 20 mm) black conduit with a purple stripe running along it. Both are at about 600 mm deep. Is there a chance that the smaller conduit with the purple stripe contains the copper phone lines? How do we find out?

Pretty sure they will only use green telecommunications ducting.

Minimum of 20mm in diameter.

If might be Copper, but its likely not Chorus'..... so you are probably out of luck..

An alternative, black pipe with an identifying stripe of the appropriate colour may be used. (e.g. for electricity, black pipe with an orange stripe.) Stripes should be at least 5 mm wide

Note 4: In telecommunications, the colours purple (TelstraSaturn Ltd) and light blue (TelstraClear Ltd) are used.

Hmm, near the end of that doc they say conduit colours for telecommunications are Green, Purple, Light Blue. Below that it also says, "Note 1: Black pipe, marked with the appropriate colour in a stripe, has also been used extensively for electricity, gas, telecommunications and water"

So based on that, black conduit with purple strip is telecommunications, right? Since the only telecommunications going to my house is copper phone lines, then this conduit could be what I'm after.
